WRINGER' RELEASE MECHANISM Carl Moon, Detroit, Mich. I Application June18, 1934, Serial No. 731,075

This invention has reference to wringer roll mechanism, particularly torelease mechanism therefor, and has for one of its objects-provision ofa release mechanism capable of being operated by means of an unusualmovement of one or both.

of the wringer rolls relative to each other and the wringer frame. Afurther object is to provide means for re.- taining the upper wringerframe portion upon the lower portion, the retaining 'means" beingquickly movable out of retaining. position by means of off-settingmovement of the roll.

Other objects will apppear in the following description and accompanyingdrawing in which Fig. 1 is a side elevational view showing an embodimentof my invention with certain .por-' tions broken away to facilitatedeposition;

Fig. 2 is afragmentary detailed view showing movements of a portion ofmy mechanism to be described.

Fig. 5 is a prospective View showing the parts included in Fig. 4 indis-assembled position and 30 Fig. 6 is a sectional View taken from line6-6 on Fig. 1.

Fig. l discloses my invention in combination with a roll wringermechanism which generally comprises a conventional wringer postdesignated l0, carrying a driving shaft H, gears I2 and a driven gearl3.

A lower wringer frame I4 is supported upon the post and is fitted with aremovable top frame member l5.

40 The upright end portions of the lower frame are preferably of hollowconstruction of a form designated 16 in Fig. 6.

A lower wringer roll I1 is mounted in the frame by means of its shaft l8journalled in the lower 45 ends of member l9 which are pivotallysupported on frame M by means of studs 20.

Shaft l8 has driving connection with gear l3 through a flexible coupling2|. The opening in frame I4 through which shaft l8 passes is of 50 suchproportions as to permit the shaft to move relative to the frame and theflexible coupling noted permits such movement without alteration of thedriving connection.

The upper ends of member I9 are fashioned 55 to have outwardly directedhooks 22 and engaging these are inwardly directed hooks 23 formed on theinner end portions of top frame [5. The function of this will beexplained shortly.

An upper wringer roll 24 is journalled in mem 5 bers 25 which arepivotally mounted at 25' upon angulated plate members 26 which haveupper horizontal portions 21. Fig. 6 will illustrate that members 26 areso proportioned as to slide vertically within the uprights of frame 14.10

A spring member 28 is mounted in the top frame by means of an adjustmentscrew 29 and has its outer ends resting upon plates 26. The spring isobviously adapted to force the-plates, carrying members 25 and roll 24,downwardlyi 15 to abut lower roll ll. However the spring is noteffective except when the top frame is re- 1 tained in suitable positionupon the lower frame which arrangement is accomplished by reason ofhooks 22 being engaged with hooks 23 of the top frame.

It will be noted, as best shown in Figs. 4 and 5, that member l9 carriesa boss 30 which engages a slot 3| formed in the adjacent side of member25.

It will also be noted that roll I! may be swung laterally about the axisof stud 20 and roll 24 about the axis of pivot 25' and that the membersare made to operate in unison by reason of stud being engaged in slot3|. 30

Fig. 2 illustrates the possible movement of member I9, and Fig. 3illustrates, in solid lines, the relative position of hooks 22 and 23when the roll is in normal central position. In this position hooks 22are obviously adapted to retain 5 the top frame in position to holdspring 28 in pressure relation. Swinging movement of the lower roll willdisplace the hooks as shown in dotted lines, whereby the top frame andpressure 40 will be released.

With the foregoing in mind it will be clear that with parts arranged asin Figs. 1 and 4 the wringer may be operated in conventional manner. If,during this operation the rolls are pushed or pulled out of verticalalignment members l9 and 25 are swung upon their pivots as indicated inFig. 2 which movement will obviously displace hooks 22, as noted, torelease the top frame.

The action described has special utility in the event of accidentalinsertion of an operators fingers between the rolls. In such an event anoperator would involuntarily jerk or pull away from the mechanism andthis movement would result in immediate releasement of pressure betweenthe rolls as above described.

While I have here shown an embodiment of my invention, numerousmodifications of its structure will be apparent to those skilled in theart. I do not wish to be limited in the matter of structure exceptwithin the scope of appended claims.

What I claim is:

1. A roll wringer mechanism having in combination a lower frame, a topframe, upper and lower wrin ger rolls supported in'a manner to belaterally movable with respect to the frames, mechanism connecting theroll supports whereby the rolls are caused to move in unitary direction,tensioning means adapted,to maintain the;

rolls in pressure relation, mechanism connected with the rolls forretaining the same in pressure relation, said mechanism beingmovable,vupo n lateral movement of the rolls, to release the tensioningmeans.

; 2. A- roll wringer mechanism having in come binationa lower frame, amovable top frame, u per and lower =vvringer rolls laterally movable inthe lower frame, tensioning means active to forcethe upper roll intopressure relation with the lower roll, mechanism connected with thelower roll for retaining'the tensioning means active, said mechanismbeing mo vable, upon lateral movement of the lower roll, to release thetensioning means, i e r ;-3, In; a roll wringer mechanism thecombination of a lower frame, a top frame releasably attached theretoupper and lower wri'nger rolls pivotally mounted in the lower frame andmech:

4. A roll wringer mechanism having in com: bination a lower frame, aremovable top frame,

upper and lower wringer rolls, said rolls being supported by means ofmechanisms pivotally supported in the lower frame whereby the rolls arelaterally movable with respect to the frame, said mechanisms havingconnections with the top frame whereby when the rolls are in oneposition the top frame is retained upon the lower frame and when therolls are moved laterally from said position the top frame is releasedfrom the lower. frame a 5 A roll wringer mechanism having in combinationa'lower frame, a removabletop frame, u per and lower wringer rolls, saidlower roll being supported by means of mechanisms pivotally supported inthe lower frame whereby the roll is laterally movable with respect tothe frame, saldmechanism having connection with the top framewherebywhen the roll is in one position the top frame is retained upon thelower frame and when the roll is moved laterally from said position thetop frame is released from the lower frame.'

said members having, portions supporting the lower roll in laterallymovable relation to the lower frame whereby, lateral movement of ,theroll brings about movement of said hooks in position to retain orrelease the top frame.
